The Missouri Clean Diesel Program strives to improve air quality by reducing emissions from on-road and off-road diesel engines. The Missouri Department of Natural Resources pursues funding opportunities for Missouri's fleet owners and operators of diesel equipment. When opportunities become available, the department lists them on this page as well as on partner websites.

2017 Missouri Clean Diesel Program (Early School Bus Replacement Program)


Eight Missouri school districts will receive partial funding for new cleaner-burning buses through the 2017 Missouri Clean Diesel Program. Four districts may purchase two buses sooner than their budgets allow, and four districts may purchase one each. The school districts will receive up to 25% of the cost of a new bus with a maximum award of $18,000 per bus. To ensure improvement in air quality, recipients must disable their old diesel engines. The department administers the clean diesel programs for EPA, which allocates funding as stipulated by the U.S. Diesel Emission Reduction Act (DERA).

The 2017 endeavor marks the third year in a row that the department's Air Pollution Control Program has focused on early replacements of school buses. Reducing diesel emissions is vital to the department’s mission of protecting public health. The program's main benefactors will be schoolchildren, an especially sensitive group. Children have respiratory and immune systems that are still developing. Asthma accounts for more school absenteeism and emergency room visits by children than any other chronic disease.

Diesel emissions contain particle pollution and precursors of ground-level ozone. Particle pollution can penetrate people’s lungs by breaching natural defenses, leading to respiratory diseases. Ground-level ozone is the pollutant of most concern across Missouri; it aggravates respiratory diseases. Missouri currently has several areas that violate or come close to violating EPA’s national standard for ground-level ozone. EPA sets a standard for ground-level ozone to protect public health and the environment.

The early replacement programs for school buses have given some communities an unforeseen bonus. Before disabling the engines of old buses, a few districts have offered them to area firefighters for hands-on training. Firefighters learn how to create new openings to extricate passengers while buses are lying on their sides.

Funding Process

The air program accepted applications for the 2017 Missouri Clean Diesel Program through Aug. 31, 2017, and in September 2017, the air program randomly selected the recipients. The air program had received sufficient funding to offer awards for twelve early replacements of school buses. Owners/operators of buses serving schoolchildren in Missouri could request funding for one or two replacements. The selected districts appear below.

Selected School Districts Number of Buses to be Replaced
Worth County R-III School District 1 bus
Branson R-IV School District 2 buses
Carl Junction R-I School District 2 buses
Gasconade County R-II School District 2 buses
Hannibal Public School District #60 1 bus
Raytown C-2 School District 1 bus
Central R-III School District 2 buses
De Soto School District #73 1 bus

The air program expects the districts to disable the engines of their old buses and purchase replacements by June 30, 2018. If one of the above-mentioned school districts declines funding or withdraws from the project, then the air program will offer the funds to the next applicant in line. Fourteen other owners of school buses also applied, and they appear in the order their names were drawn.
